I recall a while back stumbling onto a regearing guide that did the gears in a Dana 60. It was extremely detailed, pictures, 3d-graphics, it was brilliant.

but I can't find it now. I tried searching on this forum and couldn't find it, nor did a lengthy google search turn anything up. It may not have been on this forum I saw it, but one of you knowledgeable gentlemen (or ladies) is bound to know what I'm talking about, and hopefully provide me with a link?
